<p>A process for producing hollow bodies from resin reinforced with woven and/or net fabrics, consists in securing edges D1 of a plurality of textile layers D to male die part B of a mould A-B which houses an expandable bladder or membrane C. Chamber C2 formed between die part B and membrane C is connectible to a pressurised fluid source so that, after securing the textile caps D to said male die part, and introducing the latter, together with the caps, into female die part A of the mould, pressurised fluid can be introduced into chamber C2, thereby imparting a controlled pressure to said caps. Either before or after the application of pressure resin is introduced into the mould to incorporate the textile reinforcement D under pressure, which is thus maintained in a state of constraint during and after curing. <IMAGE></p> |
